Motorola, Lexicus Division Announces Speech Recognition on Advanced RISC Machines Processors
PALO ALTO, Calif. — September 9, 1996 — Motorola's Lexicus Division (NYSE:MOT) announced today that its small-memory speech recognizer designed for noisy environments has been ported to the ARM family of microprocessors from Advanced RISC Machines.
The ARM-based speech recognizer has demonstrated 99.8% accuracy in quiet, office environments. Other tests have shown it to have an average recognition rate of 96% in high noise environments such as in a car with the stereo on and the windows open.
Noise robustness, the ability to recognize the user's voice amid loud background noise, has proved to be particularly challenging for developers of speech recognition technologies. Yet noise robustness is extremely important for a variety of command and control applications in such products as:
— speaker phones
— organizers and PDAs
— home stereos
— set-top boxes
— toys & video games
— automotive and industrial applications
The application is speaker dependent and works for any language including: American and British English, French, German, Farsi, Japanese, Cantonese and Mandarin. This small vocabulary recognizer requires only two repetitions of each name or phrase to train the system.
Motorola's ARM-based speech recognizer is responsive and accurate using less than one third the processing capability of a 40MHz ARM710. The entire system requires only 20K ROM and 50K RAM for a 10 word vocabulary.
Motorola's speech recognizer runs on any member of the ARM family from the ARM7100 'PDA on a chip' to the new high performance ARM810 and StrongARM110 microprocessors. The price/performance and power efficiency of ARM processors is leading to their widespread adoption in many cost sensitive and/or portable computing applications such as mobile phones, PDAs, pagers, modems, network computers, games etc.
Robin Saxby, CEO of ARM, commented "We are delighted to see world leading application technology such as Motorola Lexicus' Speech recognition software being ported to ARM. Support of this calibre contributes to our goal of becoming the global, volume RISC standard."
"The combination of Motorola's noise robust speech recognizer on ARM's RISC processor enables us to satisfy a wide range of performance and cost requirements for handheld devices without a DSP," said Ronjon Nag, general manager of Motorola's Lexicus Division.
Motorola's ARM-based Speech Recognizer will be demonstrated at AVIOS (American Voice Input Output Systems) in San Jose, Calif., Sept. 10 – 12 in Motorola's Booth no. 18 and at the Embedded Systems Show in San Jose Sept. 17 – 19 under ARM's auspices.
Advanced RISC Machines
ARM designs, licenses and markets high-performance, low-cost, low-power consumption 32-bit RISC processors, peripherals and development tools for embedded control, consumer multimedia, DSP and portable applications.
